Decimal – Lesson 1

First of all want to thank decode for giving me the possibility of expanding the audience of my code breaking 101 lessons. Secondly I hope you all enjoy them.
So let’s begin with the real basics ok? For the more advanced students fear not more advanced classes are coming, But I prefer to make sure we are all at the same level

So this class will be about decimal

Decimal values usually go from 0-255

Normally for puzzle solving the most straight conversion you end up doing is Decimal -> ASCII (or as I call it people language)

Now the thing is not all values of decimal are good for this conversion . There are some ranges that interest us more
than others.
In this case we want 65-90 (A-Z) 97-122 (a-z) and finally 48-57 (0-9)
So seeing any code with numbers inside these ranges is normally a good sign you need to convert something from decimal to ASCII

Now you are starting to think “I have to do it by hand?” Sure… If you have nothing else to do. Honestly I use this website http://www.asciitohex.com makes my life much easier. But it is up to you

Ok time for some basic training then keeping in mind what I mentioned try and decode this string

Enjoy your lvl 1 XMP :P

NOTE – the end result will a URL not a passcode you can insert in your scanner

– There are no real items at the end since I am a player like you lot. But if I ever get access to real functional passcodes, I swear I will use them for these lessons
